First off I would like to say after 25 days I feel my dog can see a lot better but not much of visible improvement to my dog's cataract with that being said
My dog is a 12 year old 12 pound Chihuahua mix rescue. She has cataracts in both eyes after deciding surgery would be too expensive I decided to try this option. After the first week of one drop twice-daily it seemed like this was a miracle product it seemed to me like my dog's basic Vision was getting better or she was able to see me further at the park and when we are outside. View my first picture of my dog with a dog collar on.
After I read the entire instructions for the product on Amazon and the small description of product information on the box sent to me I realized this bottle is only meant to last 30 to 45 days

The second picture without a dog collar is 25 Days of usage

But in the product description it says you need 6 to 10 weeks to be able to make a determination of effectiveness. Which would require me to buy a second bottle.
30 days is the return window to be able to return this product if you are not satisfied.
So it breaks my heart to say that in 30 days I do not see effective results for my dog's cataracts.
Do I believe my dog sees better yes

would I recommend this product 2 anyone who's pet has cataract vision problems yes

If you have a bigger dog I would suggest starting off with two drops right away and if your dog's cataract is older or severe I would suggest two to three drops per application

********After 10 weeks update**********
So the update is we did not buy a second bottle but there is extremely noticeable difference in my dog's eyes. I have where did the 10 weeks to see what the actual results were with one bottle and I truly recommend 2 bottles depending on the severity of your dog's vision issues. But I truly believe it work and I tell all my friends and family and whoever will listen to me to please buy this product for their dog. It is a great wave to help with your dog's vision problems without having to pay the expensive surgery. If you are considering this even a little bit please by the product it's unbelievable how it worked

My dogs eyes are much clearer after a month now. We saw results the day after the first drops, our dog stopped bulging her eyes to see. It seems she likes when i do her doses, she seems to feel better and even do some zoomies after.
It is a bit pricey but I was willing to try for my dogs sake. Glad I did. Sight is very special for anyone.

They work just like they say. The only thing is I think this will have to be a rest of there life drops because we ran out and it got just as bad as it was if not worse so if this is an option for you and your pet catch it early as soon as you see a change use it religiously and it will help if not it will prolong the cataracts for a long time nobody knows the long term effects though, cure I don't know maybe. just have it delivered monthly or get the three pack you will use it. Just don't run out it's like starting all over again. We noticed a change first day a big change first and second week. By a month I think it was working the best it could for our dog we didn't catch it early and the good thing was it wasn't getting worse while he was on it. If you missed one application that was ok but don't miss to many three to four drops in each eye a day three times a day if real cloudy it's worth every penny just to know and see the difference in your pet

hopefully it does what it claims to do and helps my baby boy see a little better. He still has a lot of life left in him so hopefully it will help him..

Oreo had cataract's at the age of 17. One was very large, so I had him looked at to get a recommendation for cataract surgery and called the surgeon's office to get information. Of course the cost was over $10,000 and a lot of follow-up visits and demanding home care. Being careful with my money and my boy's safety I looked on a .gov website to see the latest studies. Bottom line the lumen pro had everything the .gov website recommended. This is my third purchase. The first only lasted about 5 weeks and I noticed minimal improvement, however, I purchased again (it is recommended by the company that it would take 6 -8 weeks to notice an improvement). And, I did. My boy's large cataract is minimal and he sees (which is very important because he is also deaf) every hand signal I give him. I am purchasing the third because I will continue to place at least 1 drop in each eye every day. If you purchase this product please put at least 2-3 drops in your baby's eyes (I only placed one at first) to get a nice head start. Good luck!
